LOOK FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 255,573, dated March28, 1882.

Application filed January 20, 1882. (No model.) Patented in BelgiumMarch 15, 1880, and December 15, 1880.

To all whom it may concern:

Be it known that I, EDOUARD BLED, of Paris, in the Republic of France,have invented certain new and useful Improvements in the Lock Mechanismof Fire-Arms, of which the following is a full, clear, and exactdescription.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents a vertical longitudinal section of a fire-arm havinga revolving cartridge cylinder or chamber, and showing the hammer athalf-cock. Fig.2 is a similar view of the same, in part, with the hammerat fullcocL'. Figs. 3, 4, 5, and 6 are views of details detached, Fig.3being a side view of the hammer, Fig. 4 a side view of the trigger, Fig.5 a side View and longitudinalsection of thepawl which operates thecartridge-cylinder, and Fig. 6 a side view and plan of the mainspring.Fig. 7 is a side view of the several details, in part, in their relationwith each other when the spring is in the act of bringing the hammer tohalf-cock.

This invention, although applicable to firearms generally, is moreparticularly designed to be applied to rev olvers,and will here bedescribed accordingly.

The invention consists lin certain combinations, with the hammer, of thetrigger of the fire-arm, whereby intermediate parts for controlling thehammer by the trigger are dispensed with, and the trigger acts directlyin a very simple and perfect manner upon the hammer to raise or draw itback.

The invention also consists in a peculiar construction and arrangementof the mainspring, including a secondary spring formed in or out of themainspring, and operating to bring the trigger under the hammer afterthe hammer has been brought to half-cock.

A is the stock of a revolver, B its barrel, and Otherevolvingcartridgecylinderorchamber.

D is the hammer, and aits pivot. Said hammer is formed or provided witha lower front projecting catch,b, and with a back lower projection, c.

E is the trigger, provided with an upper back projection, 61, having anotch in its end, and arranged so as to beraised by the projectingcatch 1) of the hammer when the hammer is acted upon directly by thethumb to work it back.

Pivoted to the trigger is the pawle, by which the cartridge-cylinder Gis intermittently rotated to bring its cartridge-chambers successivelyin line with the barrel. Said cylinder is held in position by aprojection,f, on the trigger engaging with any one of a series ofnotches in the cylinder, as shown in Fig. 2.

G is the mainspring, which is a. double one havin g upper and lower mainarms or branches. The upper branch acts directly upon or under thehammer,while thelower branch is extended, so as to act directly upon acam, g, formed in or on the pawl e; or when the fire-arm is not arevolver, then the lower branch of the main-l spring acts directly onthe trigger. As here shown, however, the mainspring serves to keep thesaid pawl in engaging contact with the cartridge-cylinder, and thetrigger is also controlled by the down ward pressure of the sprin g.

The lower branch of the mainspring is of a flattened construction backof its extension, which operates upon the pawl and trigger. Thisflattened portion h of the spring is beveled off at its forward end, asshown in Fig. 6, and has alongitudinal cut made in it to form in or outof the mainspring a secondary spring, i, which has arounded forwardextremity. The object of this special. construction of the mainspringwill be hereinafter explained.

The action of the lock mechanism is as follows: When the trigger E ispulled back by the finger a lower projection, k, on its rear portioncatches under the projecting catch 1) of the hammer and raises or worksback the hammer until the projection 70 escapes from such contact, whenthe hammer will be released and be brought down or acted upon by thepressure of the upper branch of the mainspring to fire the cartridge.The finger is then released from the trigger, which is returned to itsformer position by the action of thelower branch of the mainspring. Whenthe trigger is thus allowed to return to its original position the thesecondary spring't' first comes in contact increased power to bring thepro ection c a lit- 7 the trigger, it be drawn back by the thumb aplowerbranch vof the maiuspring, as it comes down, brings its flattenedportion h in contact with the back lower projection, c, of the hammer;but as the forward extremity of the secondary spring twhich forms acomponent part of the mainspring, protrudes and is rounded, while thatof the flattened portion his beveled,

with the projection c of the hammer, and is slightly flexed, as shown inFig. 7. As the downward motion of the lower branch of the mainspring iscontinued, however, the relative angle'ot' the projection c of thehammer and flattened portion h of the mainspring is changed, and thesecondary spring 11 acts with tle lower and to press it away from thefiattened portion h of the mainspring, as shown in Fig. 1. This providesfor a slight back motion of he hammer taking place when the projection kof the trigger abuts against the projectin g catch bot the hammer, andthe trigger is allowed to pass again under the hammer when the hammer isat halt-cock. The projection is of the trigger passes under the catch bwhen the extremity of the projection 01 of the trigger comes over or incontact with the top of the projection 11 of the hammer, as in Fig. 1.In this position of the parts the hammer is at halt cock, ready for thenext operation.

11f, instead of the hammer being worked by plied to the top of it, theoperation would be as follows: The projecting catch 1) of the hammerwould lift the projection d of the trigger l mer, I), having frontcatch, 11, near the lower end, the spring G, having upper and lowerbranches, and the trigger E, having an upper back projection, (I, withnotch in its end, and

' a lower rear projection, k, as and for the pur-.

pose specified.

2. The combination, with a spring having the beveled flattened portion hand the hammer having the back lower projection, c, of the secondaryspring 2', rounded in front, whereby the projection c is pressed awayfrom portion h of the mainspring and a slight back motion allowed to thehammer, for the purpose specified.

3. The combination, with the hammer D and the trigger E, constructed andarranged for operation with each other, as described, of the mainspringGr, having upper and lower branches, and having its lower branchconstructed with a flattened portion, h, and with a secondary spring,2', for operation on the hammer, es-

sentially as set forth.
